CARL F. iBUCK, OF SA T LAKE CITY, UTAH.

PRINTING-PRESS.

To all whom it may concern:

Be it known that I, CARL FfBUoIQa resident of Salt Lake City, in thecounty of Salt Lake and State of Utah,

have invented certain new and useful Improvements in Printing-Presses;and I do hereby declare the following I to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

My invention relates to improvements in printing presses, and moreparticularly to cylinder presses, an object of the invention beingto'provide anautomatic cylinder printing press for flat type withimproved cylinder movable across the same, comprising light-movableparts capable of a very high speed, and at the same time requiring verylittle power to run the press and which is built on much more simplelines than other cylinder presses in use at the present time.

A further object is to provide improved mechanism for automaticallymoving the type out of the path of the cylinder when the latter fails totake a sheet to be printed upon. 2

A further object is to provide improved inking mechanism operated by thecylinder mounting. I

s A further object is to provide improved paper feeding and ejectingmeans and improved means for transmitting motion to all movableparts tocompel them to act in unison and at the proper time.

With-these and other objects in view, the invention consists incertain-novel features of construction and combinations and arrangementsof parts as will be more fully hereinafter described and pointed out'inthe claims;

In the accompanying drawings, Figure 1 is a top plan view. Fig. 2 isa'v'iew in side elevation. Fig. 3 is a view in front elevation. Fig.4 isa view in section on the line AA oiFigs. 1 and 2. .Fig. 5 is a view insec tion on the line B.B of Figs. 1 and 3 showing the impressioncylinder after it has-taken a-sheet of paper and is passing over theface of the type. 40

Fig. 6 is a view similar to Fig. {showing impression cylinder inposition to take sheet of paper from' feed table. similar to Figs. 4 and5 showing impression cylinder after it has taken a sheet of paper and ispassing under and lifting up hinged portion of feed table. Fig. 8 a viewin section on the line -0 of Figs. 1 and 3 show.-

ing'rollers just starting to pass'over the face of the type. Figs: 9 and10 showthe gear, wh eels 'a nd inking rolls thereon, and Figs. 11, 12and, lia -"are enlarged detail 1 represents a tuting the frame-worksupport of my improved mechanism. These :standards 2 are 'made withopenings to Specification of Letters Patent.

receive the cylindrical ends of a hollow connecting axle 3 securelyfastened to the standards and secured against turning by clamps 4. Largegear wheels are mounted to turn about the cylindrical end positions ofaxle 3 and are driven by-pinions 6 in mesh therewith and secured upon adriven shaft 7 having a pulley 8 thereonto receive motion from anydesired motor, and the turning of the gear wheels 5 serves to drive allworking parts of my improved printing press as will be more fullyhereinafter set forth. The axle at its intermediate 'portion between thegear wheels. 5, is made in the form of a supporting table, as shown mostclearly in Figs. 4 and 8, and'will be hereinafter-referred to as thetable portion' of axle 3. This table is provided at four points withopenings in which four vertically movable pins 9 are mounted and arescrew threaded at their upper ends to screw into internally threadeddepending cylindrical lugs 10 on the under face of a plate 11 supportingthe type chase 12. Y-Th e pins 9 are made with angular enlargements 13to receive a wrench and facilitate their adjustment in the lugs 10 andsaid lugs are made with movable thread .bearing blocks 14 which areadjusted by set screws 15 to clamp the pins 9 and prevent-anypossibility of accidental turning movement thereof after being properlyadjusted.

In horizontal recesses 16 in the tablepoljtion of axle 3 extending belowthe rounded onbeveled lower'ends of pins 9, horizontal supporting pins17 arelocated and are beveled or contracted at their outer ends to formcams to raise or lower the pins 9 and plate 11 and coiled springs 18 arelocated on pins l7 and bear against annular shoulders 19 thereon toexert pressure on the pins 17 to force them inward when perniitted.

' A shaft 20 extends longitudinally through the hollow axle 3, ismounted to turn therein; and opposite to the inner ends of the pairs ofhorizontal pins 17, is-pro-g vided with double cams or eccentrics 21-,which latter:

are rigidly secriredtdthe shaft 20 and when'in one ,position hold, thepins 17 projected outward to support the type chase in its normaloperativeposition, but when the shaft .is permitted to be turned by a,coiled spring 22 thereon, the cams-or eccentrics 21 will permit thesprings 18 to draw the pins 17 inward and compel the plate 1.1 and typeto-fall by gravity to a position below itsnormal operative position.

A crank'armt23 is secured onone end of shaft 20 and isnormally heldfby'a pivoted dog 24, which latter is released by mechanism tobe hereinafterdescribed, when my improved impression cylinder 30 fails to take a sheetof paper tob'e printed upon.

The gear wheels 5 above referred to, are connected by c ross rods whichcompel them to move'together as a movable carriage or carrier and saidgear Wheels are made with alined radial s10t :27, in'which bear in'gboxes 28 are mounted to'slide and coiled springs pelling the cylinder'and shafts 29 to turn together and the shafts to act as trunnionsupports for the cylinder ends.

Pinions 32 are secured on shafts 29 close to the ends of cylinder 30 andmesh with racks 33 secured to stationary axle 3, and said racks are ofcircular form throughout their greater portions but have horizontal orflat portions which are located parallel with the face of the type 34.

On the outer ends of shafts 29, rollers 35 are secured and run on tracks36 of the same shape, and disposed like racks 33. The tracks 36 aresecured to standards 2, and the tracks 36 and rollers 35 are just theproper size to' allow the pitch lines of pinions 32 to reach the pitchlines of racks 33. i Horizontal guide bars 37 are secured to the upperends of standards 2 and are located above and parallel with the flat orhorizontal portions of tracks 36, and

said bars 37 arespaced from tracks 36 a distance ap+ proximating thediameter of rollers 35 to hold the latteron tracks 36 and the pinions 32on racks 33 during the horizontal movement of the impression cylinder,to insure a proper contacto'f the paper sheet with the sm A rod 38 ismounted in tubular shafts 29 and extends through the impression cylinder30 and projects out beyond the end of one tubular shaft 29 as shown. Asleeve 39 is secured on rod 38 in cylinder 30 and a coiled spring 40 islocatedon the rod and bears at one end against a shaft 29 and at itsother end against the sleeve 39 to normally hold the end of rod 38projected outward, and this outward movement of the rod-is limited by acollar 41 secured thereon. A triangular plate or arm 42 is secured tosleeve 39, projects up through a slot in cylinder 30 and is provided atits apex or end with a rounded lug or roller 43 located in a spiral orcam groove or slot 44 in a sleeve 45 secured upon a shaft 46, the lattermounted to turn in bearings 47 in a longitudinal recess in cylinder 30and provided with a series of gripper fingers .49. A coiledsp'ring 49 islocated on this shait 46, is secured at one end to the'shaft andnormally holding the gripper fingers'49 in position to clamp a papersheet to the impression cylinder. By this,

construction and arrangement of parts it will be seen that when theprojectingend of rpd 38 engages an elongated cam enlargement 50 on astandard 2, the rod will beforced inward, and the plate or arm 42 willmove and compel sleeve 45 and shaft '46 to turn, by reason of theengagement of the end of the arm 42 in spiral groove or slot 44, andthereby move the gripper tingers 49 back into a recess 51 provided inthe cylinder,

as shown in Fig. 6, so that when the sheet is fed to the cylinder fromthe platform the gripper fingers will be out of the way, but at theproper time the rod 38 will have passed the cam enlargement 50 and thesprings 40 and 49 will return the parts to their former normalpositions, compel the fingers to grasp the end of the sheetto be printedupon and after the sheetis printed upon and the cylinder reaches thepredetermined po-- sition, the projecting end of-rod 38 will engage theend the same, printed side up, into a receptacle 54 provided for thepurpose.

The gear wheels 5 are provided with three parallel slots 53 havingbearings 54 which are mounted to slide in the slots and coiled springs55 are located in the outer ends of the slots and exert inward pressureon the bearings and on inking rolls 58 having their tru'nnions 59located in thebearings and provided with small wheels 60 mounted to runon tracks 61 secured to and conforming in shape to the racks'33, thesprings 55 serving to hold the wheels 60on their tracks 61 andcompelling the inking rolls to move across the type 34 to ink the same.v

with slots 53 and arranged between the slots 53. Bearings 63 are mountedto slide in the slots 62 and coiled springs 64 connect the inner ends ofthe slots 62 with the bearings 63 to exert an inward pull on thebearings 63 and on vibrating rolls 65, the elongated trunnions ofvibrating rolls against the inking rolls 58.

In advance oi, and in rear of the slots 53 and 62, slots 66 are locatedin gear wheels 5 and bearings 67 are 'mounted to slide in the slots 66and are pressed inward by coiled springs 68in the outer ends of theslots to hold in proper position inking rolls 69, the trunnions of whichlatter extend through the bearings and are provided with wheels 70 torun on tracks 61 but are located in a different plane from the wlieels60 so that wheels 60 and 70 will rup over different parts of tracks 61.Slots 71 are provided between slots 66 to slidvibrating-rolls 7 3contacting with rolls 69 and springs vibrating rolls in contact withinking rolls 69.

75 represents a curved ink plate having webs 76 made dovetailed tofitLin dovetailed grooves in the bottom of the table portion of axle 3and are secured in place therein'by set screws. i

The ink receptacle 77 comprises a three sidedlframe of the inkreceptacle formed by a roller 78 the'trunnions 77 and one of whichtrunnions which projects through the receptacle, is provided on itsouter end with a star wheel 79 which at every revolution of the gears 5is engaged by a lug 80 on one of said gears to partially rotatethe-roller 78 and present a new ink face to the ink rolls '69 whichtouch the same and the ink thus received is smeared by the vibratingrolls 73 and is deposited on ink plate 75 and from the latter the rolls58 receive the ink and pass across the type to ink the same. A springplate 81 constitutes the bottom of receptacle 77 and is held up againstroller 78 by thumb screws 82 and the receptacle is held in operativeposition by pins '17 and when the latter move inward to drop the type,the ink receptacle will also move out of the path of the ink rolls 69. pv

Cam enlargements 83 are provided on tracks 61 at the ink receptacle 77so that the wheels 60 of ink rolls 58 will hold the latter away fromroller 78 but these {anlargements are out of the path of wheels 70 anddo not interfere withth'e contact of rolls 69 with roller 78 and ofenlargement 50 to release the printed sheet and drop Two slots 62 areprovided in gear wheels 5 parallel which are mounted in the bearings soas to hold'they ingly mount bearings 72 supporting the trunnions oipivotally secured-to axle 3 as shown, and the'outerside I of which beingsupported in the end walls of receptacle 74 are located in the outerends of slots 71 to hold the as the slots 66 are too short to permit therolls 69 to engage the type, they will be held away from the type andonly rolls 58 will come into contact with the type.' The crank arm 23above referred to is provided near its end with a sleeve 84 in which apin 85 is held at right angles to the arm, and a similar pin 86 issupported in a sleeve 87 on the dog 24. This dog 24 is pivotally securedto the frame and held in normal engagement with the arm 23 by a spring24 and is released by a cam .15] on a gear wheel 5, as will more fullyhereinafter appear. A shaft 87 is supported in bearings 88 on a standard2, is located inan inclined position, as shown, and held againstlongitudinal movement by a clamping collar 89 and fingers 90 and 91 aresecured to said shaft 87 and project in opposite. direction, one beingshown over the pin 85, with the crank arm 23 in its ordinary operativeposition. On the upper end of shaft 87 a forked bracket 92 is securedand for convenience of reference 1 will designate the two arms orfingers of the bracket 93 and 94, and a spring 96 holds the shaft 87 inposition.

Securely fastened to standards 2, are brackets 99 and 100, to which a.frame 101 is secured and supports a horizontal metal plate .102 forminga portion of a paper feed table. A short shaft 103 is secured at one-endto a frame 104 and is journaled in'bearings 105 and 106. This shaft ismade angular throughout its length, save at its bearing supports, and asleeve 107 having an angular bore is mounted on this shaft 103 and isprovided with arms 108 and 109 to engage the fingers 93 and 94 as willbe hereinafter explained.

Above shaft 103and parallel therewith, a shaft 112 is supported inbearings 1.13 and held against accidental turning by a coiled spring 95:The shaft 112 is also made angular throughout except at its bearings,and has an arm 114 secured thereon and normally resting on a lug 96 onbracket 99 to limit the turning movement of the shaft 112 and-a cam 111is secured on shaft. 112 and located between pins 1 10 on sleeve 107. Anangularly bo'rcd sleeve 115 is located on shaft 112 is secured by a setscrew 116, and provided with a rearwardly projecting arm 117 and anopening 1 18 is provided in the sleeve 1 15 to accommodate a crank arm126 having an angular hole to receive shaft 112. This sleeve 115 alsoforms a journal on which a forked bracket 119 is fulcrumed, the forwardopen end of said bracket supporting a wheel 122 and the rear closed endof the bracket lying below arm 117. The wheel 122 is provided at theupper portion of its periphery with a bifurcated lug 123'in which oneend of a rod 125 is secured, the rear end of said arm being connectedwith the upper end of crank arm 126. 3

While short shaft 103 serves as a hinge for one side of frame 104, ashort shaft 127 at the opposite side thereof serves a like purpose. anda plate 124 secured on frame 104 constitutes the front portion of thepaper feeding platform and lugs 129 on brackets 99 and 100 limitdownward movement of this hinged .portion of the platform.

A shaft 130 is mounted in bearings 128 on'frame 104 and is provided atsuitable intervals with jogging fingers 131 and also has an arm 132secured to one end and a collar 1.33 on its other end to hold the shaftagainst longitudinal movement.

One of the gear wheels 5 is provided with a radial slot 145, in which asliding block 146 is mounted and a 'up against the same.

and a tapered lug or enlargement 150 is located beside lug 148. A cam151 is secured to this same gear wheel 5 and is provided with a taperedlug or projection 152, the operation of these lugs being hereinafterpointed out in the description of the operation of the paper feedingmechanism.

On one rod 26 connecting gear wheels 5 and located at one side of theimpression cylinder 30, fingers 153 and arms 154 are mounted and are allconnected to move together, by a rod 155 passing through them. The endsof arms 154 are held against the hubs of pinions 32 by means. of aspring 156 located on the rod 26. On the rod 26 at the other side ofimpression cylinder 30, fingers 157 and arms 158 are located andconnected by a rod 159 passing through them and the ends of arms 158 areheld against the hubs of pinions 32 by a spring 160.

The type chase above referred to as being supported on plate 11, is heldin place by springs 134 and clamp 135. The clamp 135 is held by a screw136 which passes through it'and is provided with round projections 137at its ends, journaled in bearings 138 on plate 11'. On one of the roundprojections 137 is a set collar 139 and the oth or round projection ismade angular to receive 'a wrench and at the ends of clamp 135 are guidebars 140 which slide in angular slots 141 in bottom of plate 11.

The operation of .my improvements is as f llows: When the press isstarted, a sheet of paper is deposited on the feed table or platform andis pushed up against jogging fingers 1.31. The impression cylinder 30which is now being carried around by gear wheels 5 is being alsorevolved by its gears 32 running on rack 33, and is. carried up underhinged part of the feed table to a position as shown in Fig. 6. The rod38 which passes through said cylinder has been pushed in by the camenlargement 50 on standard 2, which by the mechanism above.

' described, throws the gripper fingers 49 back to the position shown inthis view (Fig. 6). When the cylinder moves slightly further the rod 38will move off enlargement 50 and permit the gripper fingers to movethrough recesses in the feed table and grasp the end of the paper sheetthereon. Previous to this operation, the jogging fingers 131, areelevated by means of arm 132 which is engaged, and elevated by the hubof a pinion 32 coming As the impression c ylindcr 30 moves upward itlifts the forward hinged part of the feed table up against wheel 122, asshown in Fig. 7 which movement of the hinged table also serves to turnshaft 103. The sheet of paper is now being pulled off the feed table andby its contact with wheel 122 causes the latter to turn, and as thewheel is connected by rod 125' with crank 126 the shaft 112 will beturned and cause its cam 111 to move sleeve 107 out to the end of shaft103 to bring itsarm 109 out under finger 94 of bracket 92'securcd onshaft 87. As the sleeve 107 is turned by means of shaft 103 it pressesarm 109 up against fingcr 94 and rocks shaft 87. This rocking of shaft87 causes finger 91 to push pin 85 inward, as it is assumed that thecrank arm 23 is in the position shown by dotted lines in Fig. 2. Thispin 85 is engaged by the projection 148 on sliding block 146 in gearwheel 5 which carries crank arm 23 to the position shown in full linesand as this movement of crank arm 23 turns shaft 20andEcQmpolsvthceccentrics 21 to forcemins 17 out-..

ward and elevate pins ii, the type chase-.rrill be moved up toitsgnormalprintingposition. .Whenthe cranlzarm has moved to this positiomntheblock 146' strikes a.v projection not shownon the frame .work.whiehcausesv the block, 1/16 to move in its slot:and releesepinfifi and thelatter is moved outwardto its thermal-position bythe tapered projection150. ,;'.The arm 23 when .moved to this position is caught by dog 24 andheld.

: It will now. be,seen-that. -,ii a sheet of paper. is not caught andpulled off the feed tablebythe gripper... fingers 49, the'wheel 122; isnot revolved, .there ore the.- shat, l12 with cam- 111E thereon, is notrevolved and the sleeve 107: is. not moved out to the end-of shaftl03.

Hence. when shaft -103.-turns the arm l08-will engage intothe-path ofcamlol which strikes the alatterand forces the .dog downward, releasingicrarykarm fifi'and permitting the latter to move to the positionshowmbydotted lines; .in.Fig. 2. .This causes the. type chase-to dropas aboveexplained .and the impressioncylinder will pass-over the same-withoutoontactwith the type. The movement of crankarm 23 is limitedhy an en-:

largement on the frame. It will thus be observed that when theimpression eylinder'is taking the paper regularly the type are held up,but it the cylinder. fails to take a sheet of paper,.the type will beautomatically dropped down out of the path of the cylinder andromaininsuch position untilthe cylinder again properly.

takes a sheet of paper to be printed upon.

When the impression cylinder takes a sheet of paper from the icedtable,..it moves forward and is caused to turn by the mechanismexplained. Thisrolls the sheet around the cylinder, which latter nowrolls over the face oi thetype as shown in Fig: 5. After the sheet hasbeen printed, the cylinder moves to the position shown in Fig. .8. Herethe gripper fingers are thrown back by means of the rod 38 engaging camenlargementfiO and the sheet is released from the cylinder and is rolledoff above explained, when the-type is dropped because the impressioncylinder failsto take :a sheet of paper the ink reservoir moves back tostop the supply of ink. It will be noticed that the tracks 61 are. asmaller radius than the pitch line of racks 33 which allows theimpression cylinder 30 to pass theink supply roller 78 and plate withoutcontact with either A great many slight changes might be made in thegeneral form. and-arrangement of the parts described without departingfrom my invention, and hence I do not restrict myself to the precisedetails set forth but consider-myself at liberty to make such slightchanges and alterations as fairly fall within the spirit and scope of myinvention.
